Sebaceoma is a benign sebaceous neoplasm that consists of variably-sized lobules in the dermis. Unlike sebaceous adenoma, the lobules in sebaceoma lack organization and are composed of a predominant population of basaloid cells that are haphazardly admixed with a small number of mature sebocytes. Rare cases show reticular, cribriform, or rippled patterns (as seen in this case) and nuclear palisading resembling Verocay bodies. Image courtesy of: T Fujisawa, MD, Sapporo City, Japan.
